JAI X-server Java 1.4 Security Problem.

Hi,

We have a problem with a WOApp deployed on XServe. Our WOApp is using
JAI (Java Advanced Imaging).
When we start our WOApp using the command-line, everyting is fine and
all JAI call returns as excpected.
When we start the same WOApp with JavaMonitor, we got a "No instance
available" at the first call to JAI.

The problem occurs after we install the last "Securities update" on
XServe. (SecurityUpd2003-12-05Jag.pkg, SecurityUpd2003-12-19Jag.pkg).

I read that some security configuration is needed to run JAI correctly.
The problem is that we didn't install JAI as recommended by sun because
we are on MACOSX. We just install some jars in the java extension
directory.

Here is what I read in the sun documentation :
----------- Sun doc -----------
If $JAI is the base directory where Java Advanced Imaging is installed,
create a text file named $JAI/policy containing the following:
grant {
     // Allow everything for now
     permission java.security.AllPermission;
   };
---------------------

The problem is that I don't have a $JAI directory since we didn't
install it as excepected by sun.

My question is the following :
How can I do the same thing without $JAI directory ?

Benoit
